Arranges the point groups G0, G1, G2, G3 ... On the predicted travel locus G while keeping a constant interval shorter than the length of the vehicle body.

The length and width of the vehicle body approximated by this frame are set to values equal to the maximum values of the actual length and width of the vehicle body, respectively. Finally, the CPU 1 converts each of the group of frame bodies arranged on the predicted travel locus G into a bird's-eye view when a bird's-eye view is made from a position of a certain height set on the origin, and writes this in the screen memory.

者は的確に予測できる。The bird's-eye view of the vehicle body row written in the screen memory 4 by the CPU 1 is periodically read by the display control unit 5 and supplied to the projector 6, where it is projected on the screen 7. The bird's-eye view B1, B2, B3, ... Of the vehicle body row projected on the screen 7 is reflected by the screen 7 and jumps into the driver's visual field. As a result, the driver can see the bird's-eye view B of the vehicle body row projected from the projector 6.
1, B2, B3, ... And the scenery of the road in front of the vehicle are superimposed, and the scene as illustrated in FIG. 1 is seen.
Since the width of the vehicle body is displayed in this way, the driver can accurately predict whether or not the vehicle can successfully turn through a road with a narrow sharp curve.

もできる。When the driver inputs a vehicle type or the like from the keyboard 8, this is converted by the CPU 1 into the width or length of the vehicle body and registered in the data memory 3. The dimensions of the vehicle body registered in the data memory 3 are used for subsequent drawing. When converting the plan view of the vehicle body row into a bird's-eye view, the CPU 1 changes the height of the viewpoint placed on the origin according to a command from the keyboard 8 to change the bird's-eye view according to the driver. The CPU 1 uses the predicted traveling trajectory G of the center of gravity.
When arranging the vehicle body rows on the upper side, the arrangement can be performed in consideration of the angle (sideslip angle) formed between the predicted traveling locus G and the center line of the vehicle body.

Further, instead of arranging the point clouds at a constant geometric interval, the point groups G0, G are arranged at a passage position at a constant time interval, for example, 0.1 second intervals.

して表示する。The CPU 1 predicts a position where the vehicle speed becomes zero, that is, a stop position of the vehicle in a state where deceleration is performed by the brake operation. In this case, the predicted travel locus displayed by the bird's-eye view of the vehicle body row ends at this stop position. In particular, the CPU 1 emphasizes and displays the predicted stop position on the predicted travel locus by blinking or another method during sudden braking in which a deceleration (negative acceleration) equal to or higher than a predetermined value occurs.

Specify by emphasis. In this way, by displaying the last frame indicating the stop position with emphasis over the others,
Whether the vehicle can be stopped immediately before an obstacle or the like, that is, the necessity of avoidance by dangerous steering can be accurately predicted.

どで表示される。It is also possible to display the predicted traveling locus in different colors or patterns according to the values of traveling speed and acceleration.
For example, when the traveling speed is less than the predetermined value, the predicted traveling locus is displayed in green, which means safety, the display color is changed to yellow to call attention as the traveling speed increases, and the display color becomes even more noticeable when the speed further increases. The color is changed to red, which strongly calls attention. Not only the display color, but also a striped zebra pattern that draws a strong attention according to the value of running speed and acceleration.

方法としては、以下のようなものが考えられる。In the vehicular display device of the present invention, a part of the scenery in front of the vehicle is hidden by the predicted traveling locus displayed by the head-up type display device, so that a roadside bicycle or a pedestrian is overlooked. There are fears. In order to avoid such an inconvenience, it is effective to keep the display of the predicted traveling locus to the minimum necessary. For this purpose, in the example of FIG. 4, the front and rear line segments may be omitted and the parallel two line segments showing only the lateral width of the vehicle may be represented instead of the rectangular frame body in which the vehicle body is closed. The following is conceivable as another specific method for reducing the number of displayed figures.

は全てＣＰＵ１によって制御される。First, when the vehicle speed is low, the length of the predicted traveling path displayed is shortened. As an example, a predetermined time,
For example, if the predicted traveling locus up to the predicted position of the vehicle after 3 seconds is displayed, the predicted traveling locus having a length proportional to the traveling speed can be displayed. If the vehicle speed is less than or equal to the predetermined value and the vehicle is traveling straight ahead, the running condition is considered to be running under congestion and the display length of the predicted travel path is set to zero, that is, the display is completely interrupted. It On the other hand, if the vehicle is turning even if the vehicle speed is equal to or lower than the predetermined value, the traveling state is considered to be entering the garage or passing through a narrow road, and the predicted traveling locus is displayed for a short time. Alternatively, the predicted traveling locus may be displayed only when at least one of the traveling speed and the acceleration exceeds a predetermined value.
The CPU 1 controls all of the above situation determination and the change of the display method according to the determination result.

Convenience is greatly improved in that not only the driver can accurately predict whether or not the vehicle can successfully turn through the road, but also the reality of the display is improved.
